I am considering replacing my old sailmaster with a new hi-tech 4 stroke nissan-tohatsu. My chief complaint with the old engine is noise. I am also concerned with reliability as it is now 8 yrs old and I know it has been used hard. How much quieter are the 4 strokes? The dinghy at the marina has Yamaha 4 stroke and it seems quieter but that is such a small boat it is hard to compare. Any opinions would be appreciated.

Thanks, Tom.

I'd venture that the Yamaha 4 stroke is essentially no louder on a C25 than on the dinghy unless it's a really small one (<5 hp). I would also not describe your 8 year old 2-stroke as being "old", but rather "just getting broken in" (unless it has been severly abused by lack of standard maintanence). However, an equally sized 4-stroke will clearly be considerably quieter.

It was not well cared for by the PO for the first 6 yrs. It is still worth a descent ammount on e-bay. I would really like a quieter motor. As the family and I travel farther with the boat it has been said by the admiral "It would be nice to have a quieter motor" Time to move on that idea! Added reliability would be a by-product.

What hp is on the dinghy? Most 5hp and smaller engines have a single cylinder, while the 8s have two. More cylinders mean less noise and vibration--the extreme being the big 225hp V-6 Hondas that sound like a V6 Accord, which is essentially what they come from. At idle, the primary sound is the water coming from the "pisser".

My motor progression has been: Yamaha 2 stroke- Older Honda 4 stroke- Yamaha 4 stroke. All in the 8-10 hp range. The new motor is by far the most quiet. Also think about the mount. An older mount & motor can have all kinds of rattles and squeks that greatly add to the noise level.

I have regularly received comments from folks on shore/other boats on how quiet the Honda 9.9 was when entering marina's......(I also like to do that at low power settings...

)

Tom, don't sell that old Sailmaster short. Pretty Penny had a 8 hp on her for 16 years and the only thing it ever received was a tune up yearly with plug changes ever other year need it or not. I did get the new Tohatsu with the new boat simply because new equals new to the General. I will tell you it is much much quieter and has less vibration and better mileage.
If you want, give me a shout, and come put a fine tooth comb on it.

O, your now famous picture rafted with sailgal sure makes her motor look a lot nicer than yours. Your Honda appears huge for no reason. Is it all sound deadening? I am surprised you can spin it in your well!

Ya, especially from the people with the big diesel rattlers in their 42' sailboats!

Dave, case of mast envie there?

Frank, it turns enough to do the job. To port is easy with prop walk, and to starboard is sufficient after I modified a small recession into the fuel locker. Also the hard fought and won beaching rudder makes a huge difference. It is effective at very low speeds, so the big boat technique of a burst of power, then idle, and letting the rudder do the job works well.

Oscar... Being single now (not part of the plan), my mast may be too big now.

But if you need more boat units for that 42, I can recommend a guy named Guido in Bayonne who is a better option than Vegas...

After 18 years of visiting Vegas on a regular basis, I can rpoudly say that the only money they get out off me is for a light meal. Gambling has never been my game....unless you want to consider going out in the wild blue yonder in a plastic bathtub, powered by wind, gambling....

I prefer the term "risk management"....

I hadn't seen that pic... One thing that's clear is the much-discussed higher freeboard of the WK (assuming Sleigh is WB). Great shot! Oh, wait... Lady Kay is a WB, too. So, what am I looking at there?

My guess is that O trailers and is lightly loaded and tropical sleigh is slipped and loaded for comfort. Suzie?

Both are WB, the main difference in weight is that I have two aft batteries, but Oscar added the AC in rear...not sure of the weight difference. Guess I'd better go on a diet...cut out some of the beer.

'Could be there is a completely different force involved here ... maybe all that hot air from Oscar is lifting up his boat ...

Man, I feel the love.....

Actually I don't think there's an issue here. If you look closely you'll see that LK is about level, and that the Sleigh is heeled slightly to port, with two people sitting on the port side and all that.

You guys must be bored......go sailing.

Nice try, Oscar... Sleigh's mast is upright--yours might be leaning ever so slightly to starboard (perhaps from the Honda). And I see you're reading and responding to our posts, so we're no more pathetic than you!
